IMPROVEMENT IN HAY AND COTTON PRESSES.

Specification forming part of Letters Patent No. 149,943, dated April21,1874; application filed March 21,1874.

To all whom it may concern:

Be it known that I, MIOHEAL MIOKELSON, of Ashland, in the county ofJackson and State of Oregon, have invented a new and usefulImprovementin Hay and Cotton Presses, of which the following is aspecification: v

Figure 1 is a side view of my improved press,

parts being broken away to show the construcbars and stirrups or pawlsby which the follower is operated, as hereinafter described.

The beam F, having follow-block G attached,

works vertically in slots in the narrow sides of the box or casing B,which is suitably secured in frame A. The lower parts I) of thecasingare detachable, to allow removal of the bale. II is a bar, havin gteeth or notches formed in its inner edge and secured to the lowercrossbar of the frame A. The bars H pass up through slots in the beam F,and are attached to the cross-beam E. I I are bars having notches orteeth formed in their outer edges, and also passing slots in the beams Fand E. To the lower ends of the bars I are pivoted the levers J, whoseinner ends are pivoted to the lower parts of the bars H. By thisconstruction'the bars I will be moved up and down by operating thelevers J. K L are two stirrups, which are pivoted to the end parts ofthe follow-beam F, between the bars H and I. One of the stirrups, as K,passes around the stationary bar H, so as to take hold of its teeth, andthus hold the follower against the back pressure of the material beingbaled. The other stirrup, L, passes around the movable bar I.

By this construction, as the bar I is raised by the upward movement ofthe lever J, the said bar I will slide up through the stirrup L and, asthe bar I isdrawn downward by the downward movement of the lever J, itsteeth catch upon the said stirrup L, and thus draw the follower downwith it, compressing the material. The teeth of the bars H I should hegraduated, being made larger at the upper end and gradually becomingsmaller toward the lower end, so that the press may be worked with thegreatest advantage of leverage where the greatest resistance isencountered. To the upper sides of the projecting ends of thefollow-beam F are attached the ends of the ropes lVI,which pass overguide-pulleys N pivoted to the projecting ends of the cross-beam E. Tothe free ends of the ropes lVI may be attached weights to balance thefollower, and thus support it, when raised to any desired point, or uponthem may beformed loops to hook upon catches 0 attached to the lowerpart of the frame'A, to hold the follower suspended at any desiredheight. To the lower part of one of the side arms of the stirrups L ispivoted a short lever, P, the inner end of which is so formed as tostrike against the other stirrup K, raising said stirrup K away from theteeth of the bar H. As the stirrup K is raised its lower part strikesagain st the stop Q attached to the follow-beam F, and is stopped, whichcauses the said lever P to raise the stirrup L from the teeth of the barI, in which position the lever, stirrup, and stop lock themselves sothat the follower may be raised freely. or projection attached to orformed upon the innerend of the lever P strikes against a stop, It,attached to the frame-work of the press, which disengages the lever Pand allows the stirrups K L to drop, ready to take hold of the teeth ofthe bars H I, when the lever J is again operated.

Having thus described my invention, I claim as new and desire to secureby Letters Patcut- The combination of the catch-lever P and stops Q Itwith the pawl-stirrups K L, the toothed bars H I, levers J J, and thefollowbeam and frame-work of the press, substantially as herein shownand described.
